Nothing is impossible..., but it is difficult to have meaning-free URIs and to support (as in ignore) other URIs. I would like ant to ignore other namespaces so that it is a civilized member of the xml community. For example the following specifies which processor deals with which element tag: <project xmlns:h="http://www.w3.org/1999/xhtml"; xmlns="ant:core"> <echo message="hello world"/> <h:html> <h:body>hello world</h:body> </h:html> </project> the above produces "hello world" as an ant script and "hello world" in an NS aware browser. > I > think it makes perfectly sense. Namespaces are to avoid name clashes. This is not the only reason for XML namespaces.

I would agree with you here. Maybe another pattern could be allowed?

What would happen if I had a Java > package on the classpath called "arbitarystring"? The definitions are appended to the definitions defined in {converted package}/antlib.xml. This is the same behaviour as definitions going into the default namespace. Peter
